Is there a program, free or otherwise, that lets you to do various algebraic manipulations, like:

- complete the square

- factorise something out

- expand something out

- etc

Doing that stuff by hand can get tedious.

I find that Sympy's simplify() often doesn't do what I want. WolframAlpha often understands what I want better. It seems like it would need non-trivial work on the UI front.

My go-to for these things is wolframalpha.com, mainly for ease of access, and the natural language interface means I don't have to remember any syntax. You can input queries like "complete the square ax^2 + bx + c" or "derivative of exp(x^3)" and get solutions, it's a real timesaver. Also, for vector/matrix derivatives, http://www.matrixcalculus.org/ is amazing.

Maxima (maxima.sf.net) is one way to do that (and a lot more). I even have it on my Android phone.
